摘　　要：给出了多通道高速数据采集系统的具体设计方案。以AD6655为例设计4路采集系统,结合实际工程应用重点分析设计了A/D采样输入端的匹配网络、采样时钟电路和LVDS数据传送等关键技术。对采集系统的主要性能进行了测试、仿真及分析。This paper proposes a specific design of muhi-channel high speed data acquisition system. Using AD6655 to design a 4-channels data acquisition system as an example and according to the practical application, this paper focuses on the analysis and design in the key technologies such as the matching network of A/D sampling input, the sampling clock circuit and LVDS（Low Voltage Differential Signal） data transfer. The main performances of the acquisition system has been analyzed, simulated and tested.
